Abstract
Aspects of the subject disclosure may include, for example, a system for generating first electromagnetic waves and directing instances of the first electromagnetic waves to an interface of a transmission medium to induce propagation of second electromagnetic waves substantially having a non-fundamental wave mode. Other embodiments are disclosed.
Claims20
A method, comprising:
- radiating, by waveguide slots of a waveguide system, instances of first electromagnetic waves by at least a portion of the waveguide slots;
- and
- combining at least two of the instances of the first electromagnetic waves along a portion of a transmission medium to induce propagation of a second electromagnetic wave bound to an outer surface of the transmission medium without requiring an electrical return path, the second electromagnetic wave having at least a dominant non-fundamental wave mode, and the second electromagnetic wave having a non-optical operating frequency.
A waveguide system, comprising:
- a transmitter for radiating first electromagnetic waves by slots of a waveguide device;
- and
- a structure of the waveguide device for guiding at least two instances of the first electromagnetic waves radiated by at least two of the slots to induce propagation of a second electromagnetic wave along a portion of a transmission medium, the second electromagnetic wave bound to an outer surface of the transmission medium without requiring an electrical return path, the second electromagnetic wave substantially having a non-fundamental wave mode, and the second electromagnetic wave having a non-optical operating frequency.
A method, comprising:
- selecting, by a waveguide system, a non-fundamental wave mode;
- enabling, by the waveguide system, a plurality of apertures of a waveguide structure of the waveguide system according to the non-fundamental wave mode selected;
- radiating, by the plurality of apertures, first electromagnetic waves;
- and
- guiding, by the waveguide structure, instances of the first electromagnetic waves to a portion of a transmission medium, wherein the instances of the first electromagnetic waves combine into a second electromagnetic wave having at least the non-fundamental wave mode selected, wherein propagation of the second electromagnetic wave is bound to an outer surface of the transmission medium, and wherein the second electromagnetic wave has a non-optical operating frequency.
